Labview Address Scheme 1

[roydm]

Labview Project
Hi,
I have a small project, 5 x 8 slot racks of Labview I/O with a cRIO 19025 controller. I won't be doing the configuration but I would like to understand how the addressing works for my drawings
I think the module slots start at zero thru 7
Do the racks also start at zero or one?
If you could please show a typical rack / slot address that would be great

Thanks
Roy

Usually a rack address is configurable.
If it was me I would take this approach.
If you have a cpu or PLC this is usually the local or rack 0
1st Remote rack = address 1
2nd remote rack = address 2
etc.....to
7th remote rack = address 7

Then your IO tag for each point can do one of two ways:
Some people (cad people take this viewpoint) use the line number on drawing to use as the tag or wire number
Some people(programmers take this viewpoint) use the IO point number on drawing to use as the tag or wire number.

Example from programmer viewpoint
Cabinet MCP01 = 1
1st remote rack = 01
slot 1 output card = O01
2st point on card start at 00? = 01
IO address = 101O0101 would equal the scheme above
I thought most brady labelers go up to 8. so there you are an 8 digit label that any old blind controls eng can read.

Cad viewpoint - Line number 4 digits then an alpha numeric number after line number for 1st wire number.
example
Line number 2100
IO address above = 12100A
